L: Inductor3.3 μH (@ VIN = 5 V, VOUT = 3.3 V); CDRH4D28C/LD series, manufactured by Sumida Corporation How to use Setting the Inductance The required inductance can be calculated by using the following equation: L= V IN − VOUT VOUT ⋅ f OSC ⋅ ΔI L VIN VIN: Input voltage (V) VOUT: Output voltage (V) … (1) fOSC: Oscillation frequency (Hz) ΔIL: Inductor ripple current (A) * Generally, ΔIL should be set to 30% to 40% of the maximum output current. For the TB7101F, set ΔIL to 0.3 A, as its maximum current [ILX(MAX)] is 1 A (min). Therefore select an inductor whose current rating is no lower than the peak switch current [1.15 A (min)] of the TB7101F. If the current rating is exceeded, the inductor becomes saturated, leading to an unstable DC-DC converter operation. If VIN = 5 V and VOUT = 3.3 V, the required inductance can be calculated as below. Be sure to select an inductor with an optimum constant by taking VIN variations into consideration. 10 2007-09-06 TB7101F(T5L1.2,F) , TB7101F(T5L1.5,F) TB7101F(T5L1.8,F) , TB7101F(T5L2.5,F) TB7101F(T5L3.3,F) L= V IN − VOUT VOUT ⋅ f OSC ⋅ ΔI L V IN 5V − 3.3V 3.3V ⋅ 1MHz ⋅ 300mA 5V = 3.7 μH = ΔIL IL 0 T= 1 fOSC TON = T ⋅ VOUT VIN Figure 2: Inductor current waveform Output capacitor The capacitance of the output ceramic capacitor is greatly affected by temperature. Select a product whose temperature characteristics (such as B-characteristic) are excellent. The capacitance value should be to more than 10μF, and set to an optimum value by, for example, enlarging the output capacitor when there is instability under use conditions ,or when there is a large ripple voltage or drop in output voltage under heavy loads. Ceramic capacitors can be used to achieve low output ripple, though it is more difficult to achieve phase compensation with ceramic capacitors because the equivalent series resistance (ESR) of ceramic capacitors is lower. For this reason, perform a careful evaluation when using ceramic capacitors. Precautions • Please select parts after confirming the actual operation in the customer set and considering the input voltage the output voltage, the output current, the temperature, the characteristics or the kind of capacitor, and the inductor. • If the voltage between the input and output is low, the influence of the on-state voltage of the switch power MOSFET is greater, causing the voltage across the inductor to decrease. For this reason, it may become impossible for the required inductor current to flow, resulting in lower performance or unstable operation of the DC-DC converter. As a rough standard, keep the input-output voltage potential difference at or above 1 V, taking the on-state voltage of the power MOSFET into consideration. • The lowest output voltage that can be set is 0.8 V (typ.). • There is an antistatic diode between the ENB and VIN pins. The voltage between the ENB and VIN pins should satisfy the rating VENB - VIN < 0.3 V • If operation becomes unstable due to switching noise under a heavy load, please mount a by-pass capacitor Ccc between the SGND pin and the VIN pin. 11 2007-09-06 TB7101F(T5L1.2,F) , TB7101F(T5L1.5,F) TB7101F(T5L1.8,F) , TB7101F(T5L2.5,F) TB7101F(T5L3.3,F) Characteristic data VOUT – IOUT 3.234 TB7101F(T5L3.3,F) Ta = 25°C 3.201 VOUT (V) 3.267 Output Voltage VIN=5.0 V 2.550 2.5 2.525 2.475 2.450 0.01 Load Current VOUT (V) 1.836 Output Voltage 1.8 0.1 IOUT 1 0.001 (A) 1.818 0.1 1.782 TB7101F(T5L1.8,F) Ta = 25°C 1.836 1.8 1.746 1 IOUT (A) VOUT – IOUT 1.854 VIN=5.0 V 1.764 0.01 Load Current VOUT – IOUT 1.854 1.818 VIN=3.3 V 1.782 1.764 TB7101F(T5L1.8,F) Ta = 25°C 1.746 0.001 0.01 Load Current 0.1 IOUT 1 0.001 (A) VOUT (V) Output Voltage VIN=5.0 V 1.5 1.485 1.47 TB7101F(T5L1.5,F) Ta = 25°C 0.1 IOUT 1 (A) VOUT – IOUT 1.545 1.53 1.515 0.01 Load Current VOUT – IOUT 1.545 VOUT (V) TB7101F(T5L2.5,F) Ta = 25°C 2.425 0.001 Output Voltage VIN=5.0 V VOUT (V) 3.3 3.333 VOUT – IOUT 2.575 Output Voltage VOUT (V) 3.366 Output Voltage 3.399 1.53 1.515 VIN=3.3 V 1.5 1.485 1.47 TB7101F(T5L1.5,F) Ta = 25°C 1.455 1.455 0.001 0.01 Load Current 0.1 IOUT 0.001 1 0.01 Load Current (A) 12 0.1 IOUT 1 (A) 2007-09-06 TB7101F(T5L1.2,F) , TB7101F(T5L1.5,F) TB7101F(T5L1.8,F) , TB7101F(T5L2.5,F) TB7101F(T5L3.3,F) VOUT – IOUT VIN=5.0 V 1.188 1.176 TB7101F(T5L1.2,F) Ta = 25°C VOUT (V) 1.2 1.212 VOUT – IOUT 1.236 1.224 Output Voltage VOUT (V) 1.224 Output Voltage 1.236 1.2 1.164 1.212 VIN=3.3V 1.188 1.176 TB7101F(T5L1.2,F) Ta = 25°C 1.164 0.001 0.01 0.1 Load Current 1 IOUT 0.001 (A) 0.01 Load Current 2.55 3.3 VOUT (V) VOUT (V) 3.366 3.333 Output Voltage IOUT = 0.2A 3.267 TB7101F(T5L3.3,F) Ta = 25°C 3.201 4 3 VIN 2.5 2.475 TB7101F(T5L2.5,F) Ta = 25°C 2.45 2 (V) VOUT – VIN 6 5 VIN (V) VOUT – VIN VOUT (V) 1.545 IOUT = 0.2A 1.818 Output Voltage VOUT (V) Output Voltage 4 3 Input Voltage 1.854 1.782 1.764 1.746 (A) IOUT = 0.2A 2.525 6 5 Input Voltage 1.8 IOUT 2.425 2 1.836 1 VOUT – VIN 2.575 Output Voltage VOUT – VIN 3.399 3.234 0.1 TB7101F(T5L1.8,F) Ta = 25°C 2 3 4 Input Voltage 5 VIN 1.53 IOUT = 0.2A 1.515 1.5 1.485 1.47 1.455 6 (V) TB7101F(T5L1.5,F) Ta = 25°C 2 3 4 Input Voltage 13 5 VIN 6 (V) 2007-09-06 TB7101F(T5L1.2,F) , TB7101F(T5L1.5,F) TB7101F(T5L1.8,F) , TB7101F(T5L2.5,F) TB7101F(T5L3.3,F) VOUT – VIN VOUT (V) 1.224 Output Voltage 1.236 1.2 IOUT = 0.2A 1.212 1.188 1.176 1.164 TB7101F(T5L1.2,F) Ta = 25°C 3 2 5 4 Input Voltage VIN 6 (V) η – IOUT η – IOUT 80 (%) 100 VIN = 5.0V 80 VIN = 5.0V η 60 60 Efficiency Efficiency η (%) 100 40 20 40 20 TB7101F(T5L3.3,F) Ta = 25°C 0 TB7101F(T5L2.5,F) Ta = 25°C 0 0 0.2 0.4 0.6 Load Current IOUT 0.8 1 0 (A) 0.2 η – IOUT IOUT 0.8 1 (A) 80 (%) 100 VIN = 3.3V η η (%) 0.6 η – IOUT 100 Efficiency 60 Efficiency 0.4 Load Current 40 20 TB7101F(T5L1.8,F) Ta = 25°C 0.2 0.4 Load Current 0.6 IOUT 0.8 VIN = 5.0V 60 40 20 TB7101F(T5L1.8,F) Ta = 25°C 0 0 80 0 1 0 (A) 0.2 0.4 Load Current 14 0.6 0.8 IOUT (A) 1 2007-09-06 TB7101F(T5L1.2,F) , TB7101F(T5L1.5,F) TB7101F(T5L1.8,F) , TB7101F(T5L2.5,F) TB7101F(T5L3.3,F) η – IOUT η – IOUT 100 (%) 80 VIN =3.3V 80 VIN =5.0V 60 60 Efficiency Efficiency η η (%) 100 40 20 20 0 0 0 0.2 0.4 0.6 IOUT 0.8 1 0 (A) (%) η 80 60 Efficiency (%) η Efficiency 0.6 0.8 IOUT (A) 1 η – IOUT VIN =3.3V 20 0.4 100 100 80 0.2 Load Current η – IOUT 40 TB7101F(T5L1.5,F) Ta = 25°C TB7101F(T5L1.5,F) Ta = 25°C Load Current 60 40 40 VIN =5.0V 20 TB7101F(T5L1.2,F) Ta = 25°C TB7101F(T5L1.2,F) Ta = 25°C 0 0 0 0.2 0.4 Load Current 0.6 0.8 IOUT (A) 0 1 0.2 0.4 Load Current 15 0.6 0.8 IOUT (A) 1 2007-09-06 TB7101F(T5L1.2,F) , TB7101F(T5L1.5,F) TB7101F(T5L1.8,F) , TB7101F(T5L2.5,F) TB7101F(T5L3.3,F) Package dimensions SON8-P-0303-0.65A Unit: mm 8 5 1 4 0.33 ± 0.05 0.05 M A 2.8 ± 0.1 2.4 ± 0.1 0.1 max 0.17 ± 0.02 B 0.05 M B 0.475 0.65 2.9 ± 0.1 0.025 S 1.12 +0.13 - 0.12 0.28 +0.1 - 0.11 S 1.12 0.8 ± 0.05 +0.13 - 0.12 0.28 +0.1 - 0.11 A Weight: 0.017 g (Typ.) 16 2007-09-06 TB7101F(T5L1.2,F) , TB7101F(T5L1.5,F) TB7101F(T5L1.8,F) , TB7101F(T5L2.5,F) TB7101F(T5L3.3,F) RESTRICTIONS ON PRODUCT USE 20070701-EN • The information contained herein is subject to change without notice. • TOSHIBA is continually working to improve the quality and reliability of its products.
