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:

SSOP010-P-0225

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
