1 / 17 page Voltage Regulators 1 AN8016NSH Single-channel 1.8-volt step-up DC-DC converter control IC s Overview The AN8016NSH is a single-channel PWM DC-DC converter control IC that supports low-voltage operation. This IC allows a stepped-up voltage output to be pro- vided with a minimal number of external components. It features a low minimum operating voltage of 1.8 V, and due to being provided in a 10-pin surface mount package with a 0.5 mm lead pitch, is optimal for use in miniature high-efficiency power supplies for portable equipment. s Features • Wide operating supply voltage range: 1.8 V to 14 V • High-precision reference voltage circuit: 1.27 V (allow- ance: ± 3%) • Supports control over a wide output frequency range: 20 kHz to 1 MHz • Provides a fixed output current with minimal supply voltage fluctuations by using an external resistor to set the output current with a totem pole structure in the output block. • Large maximum output current of ± 50 mA • Timer latch short-circuit protection circuit (charge current: 1.3 µA typical) • Low input voltage malfunction prevention circuit (U.V.L.O.) (circuit operation start voltage: 1.6 V typical) • On/off control function (active-high, standby current: 5 µA maximum) • Fixed maximum duty ratio with small sample-to-sample variations (80% ± 5%) • Adjustable soft start time provided by using separate DTC and S.C.P. pins. • Adopts a 0.5 mm lead pitch 10 pin SO flat package (SSONF-10D) • Adopts techniques for reducing noise, increasing the light load efficiency, and suppressing the maximum base current when turning on the npn transistor used as the external switching element. s Applications • LCD displays, digital still cameras, PDAs SSOP010-P-0225 Unit: mm 4.3 ±0.30 6.3 ±0.30 0.5 ±0.2 1 5 10 6 |
