描述 Description
■Overview
The AN8049SH is a three-channel PWM DC-DC converter control IC that features low-voltage operation.
This IC can form a power supply that provides two step up outputs and one step-down or polarity inverted output? with a minimal number of external components. The AN8049SH features the ability to operate from a supply voltage as low as 1.8 V, and thus can be operated from two dry-batteries.■
特性 Features
?Wide operating supply voltage range: 1.8 V to 14 V
?High-precision reference voltage circuit
? —VREFpin voltage: ±1%
? — Error amplifier: ±1.5%
?Surface mounting package for miniaturized and thinner power supplies Package: SSOP-24D
? 0.5-mm lead pitch
? 7.8 mm ×6.8 mm ×t1.9 mm
?Supports control over a wide output frequency range: 20 kHz to 1 MHz
?On/off (sequence control) pins provided for each channel for easy sequence control setup
?The negative supply error amplifier supports 0-volt input.
? Common-mode input voltage range: ?0.1 V to VCC ?1.4 V
? This allows the number of external components to be reduced by two resistors.
?Fixed duty factor: 86% However, the duty can be adjusted to anywhere from 0% to 100% with an external resistor.
?Timer latch short-circuit protection circuit (charge current: 1.1 μA typical)
?Low input voltage malfunction prevention circuit (U.V.L.O.) (operation start voltage: 1.67 V typical)
?Standby function (active-high control input, standby mode current: 1 μA maximum)
?Alternate package versions also available.
? Part No.: AN8049FHN
? Package: QFN-24
??? ????????? 0.5-mm lead pitch
????? ????? ? 5.4 mm ×4.4 mm ×t0.8 mm
■Applications
?Electronic equipment that requires a power supply system
