Product data sheet
1. General description
The GreenChip II is the second generation of green Switched Mode Power Supply
(SMPS) controller ICs. Its high level of integration allows the design of a cost effective
power supply with a very low number of external components.
The TEA1530(A) (TEA1530T, TEA1530AT and TEA1530AP) can be used in fixed
frequency converter designs for low voltage, high current applications. At low power
(standby) levels, the system operates in cycle skipping mode which minimizes the
switching losses during standby.
The proprietary high voltage BCD800 process makes direct start-up possible from the
rectified universal mains voltage in an effective and green way. A second low voltage
BICMOS IC is used for accurate, high speed protection functions and control.
The TEA1530(A) enables highly efficient and reliable supplies to be designed easily.

NXP Semiconductors
GreenChip II SMPS control IC
7.1 Start-up, mains enabling operation level and undervoltage lockout
Refer to Figure 8 and Figure 9. Initially, the IC is self supplying from the rectified mains
voltage via pin DRAIN. The supply capacitor CVCC (at pin 1) is charged by the internal
start-up current source to a level of about 4 V or higher, depending on the drain voltage.
Once the drain voltage exceeds the Vmains(oper)(en) (mains-dependent operation-enabling
level), the start-up current source will continue charging capacitor CVCC (switch S1 will be
opened), see Figure 1. The IC activates the power converter as soon as the voltage on
pin VCC passes the Vstartup level. At this moment the IC supply from the high voltage pin is
stopped (green function). The IC supply is taken over by the auxiliary winding of the
flyback converter.
The moment the voltage on pin VCC drops below Vth(UVLO) (undervoltage lockout), the IC
stops switching and performs a safe restart from the rectified mains voltage. In the safe
restart mode the driver output is disabled and the voltage on pin VCC is recharged via the
pin DRAIN.
7.2 Supply management
All (internal) reference voltages are derived from a temperature compensated, on-chip
band gap circuit.
7.3 Current control mode
Current control mode is used for its good line regulation behavior.
The primary current is sensed across an external resistor and compared with the internal
control voltage. The driver output is latched in the logic, preventing multiple switch-on.
The internal control voltage is inversely proportional to the voltage on the external
pin CTRL with an offset of 1.5 V. This means that a voltage range from 1 V to
approximately 1.5 V on pin CTRL will result in a pin SENSE voltage range from
0.52 V to 25 mV (a high external control voltage results in a low duty cycle).

7.5 Cycle skipping
At very low power levels, a cycle skipping mode activates. An internal control voltage
(Vsense(max)) lower than 25 mV will inhibit switch-on of the external power MOSFET until
this voltage increases to a higher value; see Figure 5.
7.6 Continuous Conduction Mode (CCM)
The IC operates in Fixed Frequency Continuous Conduction Mode (FF CCM). Pin DRAIN
should be connected to the high voltage rectified mains VI; see Figure 8.
7.7 OverCurrent Protection (OCP)
The primary peak current in the transformer is measured accurately cycle-by-cycle using
the external sense resistor Rsense. The OCP circuit limits the voltage on pin SENSE to an
internal level equal to 1.5 V − VCTRL (see also Section 7.3). The OCP detection is
suppressed during the leading edge blanking period, tleb to prevent false triggering caused
by the switch-on spikes.
7.8 Control pin protection
If pin CTRL becomes open-circuit or is disconnected, a fault condition is assumed and the
converter will stop switching immediately. Operation recommences when the fault
condition is removed.
7.9 Adjustable slope compensation
A slope compensation function has been added at pin CTRL; see Figure 6. The slope
compensation function prevents subharmonic oscillation in CCM at duty cycles over 50 %.
The CTRL voltage is modulated by sourcing a (non-constant) current out of pin CTRL and
by adding externally a series resistor Rslopecomp. This increases the CTRL voltage
proportionally with the on-time, which therefore limits the OCP level. A longer on-time
results in a higher CTRL voltage, this increase in CTRL voltage will decrease the on-time.
Slope compensation can be adjusted by changing the value of Rslopecomp. Slope
compensation prevents modulation of the on-time (duty cycle) while operating in FF CCM.
A possible drawback of subharmonic oscillation can be output voltage ripple.

7.10 Minimum and maximum on-time
The minimum on-time of the SMPS is determined by the LEB time (typically 400 ns). The
IC limits the maximum on-time by limiting the driver duty cycle to 70 %. So the maximum
on-time is correlated to the oscillator time which results in an accurate limit of the
minimum input voltage of the flyback converter.
7.11 PROTECT and timing input
The PROTECT input (pin 3) is a multipurpose, high-impedance input, which can be used
to switch off the IC and create a relatively long timing function. As soon as the voltage on
this pin rises above 2.5 V, switching stops immediately. For the timing function, a current of
typically 50 µA flows out of pin PROTECT and charges an external capacitor until the
activation level of 2.5 V is reached. This current source is only activated when the
converter is not in regulation, which is detected by the voltage on pin CTRL
(VCTRL < 0.63 V). A (small) discharge current is also implemented to ensure that the
capacitor is not charged, for example, by spikes. An internal MOSFET switch is added to
discharge the external capacitor and ensures a defined start situation. For the
TEA1530AP and TEA1530AT the voltage on pin CTRL determines whether the IC enters
latched protection mode or safe restart protection mode:
• When the voltage on pin CTRL is below 0.63 V, the IC is assumed to be out of
regulation (e.g. the control loop is open). In this case activating pin PROTECT
(VPROTECT > 2.5 V) will cause the converter to stop switching. Once VCC drops below
Vth(UVLO), capacitor CVCC will be recharged and the supply will restart. This cycle will
be repeated until the fault condition is removed (safe restart mode).
• When the voltage on pin CTRL is above 0.63 V, the output is assumed to be in
regulation. In this case activating pin PROTECT (VPROTECT > 2.5 V), by external
means, will activate the latch protection of the IC. The voltage on pin VCC will cycle
between Vstartup and Vth(UVLO), but the IC will not start switching again until the latch

protection is reset. The latch is reset as soon as VCC drops below 4.5 V (typical value)
(this only occurs when the mains has been disconnected). The internal
overtemperature protection will also trigger this latch; see also Figure 1.
For the TEA1530T the IC always enters the latched mode protection independent of the
voltage on pin CTRL.
A voltage higher than 3 V on pin PROTECT will always latch the IC. This is independent of
the state of the IC.
7.12 OverTemperature Protection (OTP)
The IC provides accurate OTP. The IC stops switching when the junction temperature
exceeds the thermal shutdown temperature. When VCC drops to Vth(UVLO), capacitor CVCC
is recharged to the Vstartup level, however, switching will not restart. Subsequently, VCC will
drop again to Vth(UVLO).
Operation only recommences when VCC drops below a level of about 4.5 V, typically when
the mains voltage is disconnected for a short period.
7.13 Soft start-up (pin SENSE)
To prevent transformer rattle at start-up or during hiccup, the transformer peak current is
slowly increased by the soft start function. This can be achieved by inserting a resistor
and a capacitor between pin SENSE (pin 5) and sense resistor Rsense. An internal current
source charges the capacitor to VSENSE = Istartup(soft) × Rss (about 0.5 V maximum).
The start level and the time constant of the increasing primary current level can be
adjusted externally by changing the values of Rss and Css.
V sense ( max ) – ( I startup(soft) × R ss )
I DM = -------------------------------------------------------------------------------R sense
τ = R ss × C ss
The charging current Istartup(soft) will flow as long as the voltage on pin SENSE is
below approximately 0.5 V. If the voltage on pin SENSE exceeds 0.5 V, the soft start
current source will start limiting current Istartup(soft). At Vstartup, the Istartup(soft) current source
is completely switched off, see Figure 7.
Since the soft start current Istartup(soft) is supplied from pin DRAIN, the Rss value will not
affect VCC current during start-up.

7.14 Driver
The driver circuit to the gate of the power MOSFET has a current sourcing capability of
typically 150 mA and a current sink capability of typically, 500 mA at VCC = 9.5 V. At
VCC = 15 V, the current sourcing capability is typically 250 mA and the current sink
capability typically 0.7 A. This permits fast turning on and off of the power MOSFET for
efficient operation.
A low driver source current has been chosen to limit the ∆V/∆t at switch-on. This reduces
ElectroMagnetic Interference (EMI) and also limits the current spikes across Rsense.

11. Application information
A converter with the TEA1530(A) consists of an input filter, a transformer with a third
winding (auxiliary), and an output stage with a feedback circuit.
Capacitor CVCC buffers the IC supply voltage, which is powered via the internal current
source, that is connected to the rectified mains, during start-up and via the auxiliary
winding during operation.
A sense resistor Rsense converts the primary current into a voltage at pin SENSE. The
value of Rsense defines the maximum primary peak current.
Figure 8 shows a typical CCM flyback configuration. Pin PROTECT is used in this
example for external overtemperature protection and open loop or output short circuit
protection.

(1) When VPROTECT is forced above 3 V, the protection is always latched. So the IC is not started at
Vstartup unless the VCC voltage drops below the VVCC(latch)(reset) level. This is the same action used
for external OTP compensation described in Section 7.12.
(2) External OTP for TEA1530(A); OVP and output short circuit for TEA1530T.
