Description

The TPS61032PWP, TPS6103x devices provide a power supply solution for products powered by either a one-cell Li-Ion or Li-polymer, or a two to three-cell alkaline, NiCd or NiMH battery. The converter generates a stable output voltage that is either adjusted by an external resistor divider or fixed internally on the chip.

It provides high efficient power conversion and is capable of delivering output currents up to 1 A at 5 V at a supply voltage down to 1.8 V. The implemented boost converter is based on a fixed frequency, pulse-width- modulation (PWM) controller using a synchronous rectifier to obtain maximum efficiency.

At low load currents the converter enters Power Save mode to maintain a high efficiency over a wide load current range. The Power Save mode can be disabled, forcing the converter to operate at a fixed switching frequency. It can also operate synchronized to an external clock signal that is applied to the SYNC pin. The maximum peak current in the boost switch is limited to a value of 4500 mA.

Part Number: LT1303CN8-5

Marking : 1303, 13035

Function: Micropower High Efficiency DC/DC Converters with Low-Battery Detector Adjustable and Fixed 5V

Package: DIP 8 Pin Type

Manufacturer: Linear Technology, Analog Devices

Pinouts:

Description

The LT1303, LT1303CN8-5, LT1303-5 are micropower step-up high efficiency DC/DC converters using Burst Mode TM operation. They are ideal for use in small, low-voltage battery operated systems. The LT1303-5 accepts an input voltage between 1.8V and 5V and converts it to a regulated 5V.

The LT1303 is an adjustable version that can supply an output voltage up to 25V. Quiescent current is only 120µA from the battery and the shutdown pin further reduces current to 10µA. The low-battery detector provides an open collector output that goes low when the input voltage drops below a preset level. The on-chip NPN power switch has a low 170mV saturation voltage at a switch current of 1A.

The LT1303, LT1303-5 are available in 8-lead PDIP or SO packages, easing board space equirements.
