HT77xxSA

200mA PFM Synchronous

Step-up DC/DC Converter

Features

General Description

• Low start-up voltage: 0.7V (Typ.)

The HT77xxSA devices are a high efﬁciency PFM syn-

chronous step-up DC-DC converter series which are

designed to operate with both wire wound chip power

inductors and also with multi-layered chip power

inductors. The device series have the advantages of

extremely low start-up voltage as well as high output

voltage accuracy. Being manufactured using CMOS

technology ensures ultra low supply current. Because

of their higher operating frequency, up to 500 kHz, the

devices have the benefits of requiring smaller outline

type lower value external inductors and capacitors. The

higher operating frequency also offers the advantages

of much reduced audio frequency noise. The devices

require only three external components to provide a

ﬁxed output voltage of 2.7V, 3.0V, 3.3V, 3.7V or 5.0V.

• High efﬁciency: 2.7V

5.0V upper 90%

≤

OUT

(Typ.)

• High output voltage accuracy: ±2.5%

• Output voltage: 2.7V, 3.0V, 3.3V, 3.7V, 5.0V

• Output current up to 200mA

• Ultra low supply current I_DD: 5μA (Typ.)

• Low ripple and low noise

• Low shutdown current: 0.1μA (Typ.)

• Package types: 3-pin SOT89, 3-pin SOT23 and

5-pin SOT23

Applications

• Palmtops/PDAs

The HT77xxSA devices include an internal oscillator,

PFM control circuit, driver transistor, reference volt-

age unit and a high speed comparator. They employ

pulse frequency modulation techniques, to obtain

minimum supply current and ripple at light output

loading. These devices are available in space saving

3-pin SOT89, 3-pin SOT23 and 5-pin SOT23 packag-

es. For 5-pin SOT23 package types, they also include

an internal chip enable function to reduce power con-

sumption when in the shutdown mode.

• Portable communicators/Smartphones

• Cameras/Camcorders

• Battery-powered equipment
