ZL1505 Features The ZL1505 is an integrated high-speed, high-current N-channel MOSFET driver for synchronous step-down DC/DC conversion applications. When used with Zilker Labs Digital-DC™ PWM controllers, the ZL1505 enables dynamically adaptive dead-time control that optimizes efficiency under all operating conditions. A dual input PWM configuration enables this efficiency optimization while minimizing complexity within the driver. • High-speed, high-current drivers for synchronous N-channel MOSFETs • Adaptive dead-time control optimizes efficiency when used with Digital-DC controllers • Integrated 30V bootstrap Schottky diode • Capable of driving 40A per phase • Supports switching frequency up to 1.4MHz - >4A source, >5A sink low-side driver - >3A source/sink high-side driver - <10ns rise/fall times, low propagation delay Operating from a 4.5V to 7.5V input, the ZL1505 combines a 5A, 0.5W low-side driver and a 3A, 0.8W high-side driver to support high step-down buck applications. A unique adjustable gate drive current scheme allows the user to adjust the drive current on both drivers to optimize performance for a wide rage of input/output voltages, load currents, power MOSFETs and switching frequencies up to 1.4MHz. An integrated 30V bootstrap Schottky diode is used to charge the external bootstrap capacitor. An internal watchdog circuit prevents excessive shoot-through currents and protects the external MOSFET switches. The ZL1505 is specified over a wide -40°C to +125°C junction temperature range and is available in an exposed pad DFN-10 package. • Adjustable gate drive strength optimizes efficiency for different VIN, VOUT, IOUT, FSW and MOSFET combinations • Internal non-overlap watchdog prevents shoot-through currents Applications*(see page 12) • High efficiency, high-current DC/DC buck converters with digital control and PMBus™ • Multi-phase digital DC/DC converters with phase adding/dropping • Power train modules • Synchronous rectification for secondary side isolated power converters Related Literature*(see page 12) • FN6846 ZL2004 Adaptive Digital DC/DC Controller with Current Sharing HSEL BST VDD GH PWMH Level shift Shootthrough Protection SW VDD PWML GL ZL1505 GND LSEL FIGURE 1.

The patented Digital-DC control scheme utilizes a closed-loop algorithm to optimize the dead-time applied between the gate drive signals for the high-side and low-side MOSFETs. By monitoring the duty cycle of the resulting DC/DC converter circuit, this dynamic routine continuously varies the MOSFET dead times to optimize conversion efficiency in response to varying circuit conditions. The ZL1505’s dual PWM input configuration enables this optimization scheme to be applied while minimizing the complexity within the driver device. Please refer to the ZL2004 data sheet for details on the dynamic dead-time optimization routine. The ZL1505 integrates two powerful gate drivers that have been optimized for step-down DC/DC conversion circuit configurations whose output current can exceed 40A per phase. The ZL1505 also integrates a 30V bootstrap Schottky diode to minimize the external components and provide a high drive voltage to the high-side driver device. Variable Gate Drive Current The ZL1505 incorporates an innovative variable drive current scheme that enables the user to optimize the gate drive current levels to the requirements of the external MOSFETs used over a wide range of operating frequencies. Each of the gate drivers incorporates a logic input (HSEL and LSEL) that allows the user to select the gate drive strength to 50% or 100% of the total rated drive current. With the HSEL pin connected to the BST pin, the high-side driver can deliver the full rated gate drive current; with the HSEL pin connected to the SW pin, the output current will be limited to 50% of the full rated output capability. With the LSEL pin connected to VDD, the low-side driver can deliver the full rated gate drive current; with the LSEL pin connected to GND, the output 11 current will be limited to 50% of the full rated output capability. Using HSEL and LSEL, the ZL1505 can be used across a wide range of applications using only a simple PCB layout change. Also, the VDD pin is the gate drive bias supply for the external MOSFETs. VDD can be used to vary the gate drive strength as shown for the low-side driver in Figures 9 thru 12 and for the high-side driver in Figures 17 thru 20. Overlap Protection Circuit The ZL1505 includes an internal watchdog circuit that prevents excessive shoot-through current from occurring in the unlikely event that the PWM converter places both switches in the ON position. If the overlap time between the PWMH and PWML pulses exceeds 30ns, the PWMH signal will be forced to the LOW state until the overlap condition ceases, allowing normal switching operation to continue. Start-up Requirements During power-up, the ZL1505 maintains both GH and GL outputs in the LOW state while the VIN voltage is ramping up. Once the VDD supply is within specification, the GH and GL pins may be operated using the PWMH and PWML logic inputs respectively. In the case where the PWM controller is powered from a supply other than the ZL1505’s VDD supply, and the PWM controller is powered up first, the PWM controller gate outputs should be kept in low or in high-impedance state until the VDD supply is within specification. Additionally, if the ZL1505 begins its power-down sequence prior to the PWM controller then the PWM controller gate outputs should be set in low or in high-impedance state before the VDD voltage supply drops below its specified range. Thermal protection When the junction temperature exceeds +150°C the high-side driver output GH is forced to logic low state. The driver output is allowed to switch logic states again once the junction temperature drops below +134°C.
