Detailed Product Description

WIDE-INPUT SYNCHRONOUS BUCK CONTROLLER

 

DESCRIPTION

The TPS40060 and TPS40061 are high-voltage, wide input (10 V to 55 V) synchronous, step-down con verters. This family of devices offers design flexibility with avariety of user programmable functions, including;soft-start, UVLO, operating frequency, voltage feed-forward, high-side current limit, and loop com- pensation. These devices are also synchronizable to an external supply.

 

The TPS40060 and TPS40061 incorporate MOSFET gate drivers for external P-channel high-side and

N-channel synchronous rectifier (SR) MOSFETs. Gate drive logic incorporates anti-cross conduction circuitry to prevent simultaneous high-side and synchronous rectifier conduction.

 

TERMINAL

NAME   NO.

   I/ODESCRIPTION
BP5        3   O5-V reference. This pin should be bypassed to ground with a 0.1-µF ceramic capacitor. This pin may be used wit an external DC load of 1 mA or less.
BP10     11   O10-V reference used for gate drive of the N-channel synchronous rectifier. This pin should be bypassed by a 1-µF  ceramic capacitor. This pin may be used with an external DC load of 1 mA or less.
BPN10   13   ONegative 8-V reference with respect to VIN. This voltage is used to provide gate drive for the high side P-channel  MOSFET. This pin should be bypassed to VIN with a 0.1-µF capacitor 
COMP     8    IOutput of the error amplifier, input to the PWM comparator. A feedback network is connected from this pin to the  VFB pin to compensate the overall loop. The comp pin is internally clamped above the peak of the ramp to improve large signal transient response
HDRV    14   OFloating gate drive for the high-side P-channel MOSFET. This pin switches from VIN (MOSFET off) to BPN10  (MOSFET on). 
ILIM       16    ICurrent limit pin, used to set the overcurrent threshold. An internal current sink from this pin to ground sets a voltage drop across an external resistor connected from this pin to VIN. The voltage on this pin is compared to thevoltage drop (VIN -SW) across the high side MOSFET during conduction. 
KFF       1    IA resistor is connected from this pin to VIN to program the amount of voltage feed-forward. The current fed into  this pin is internally divided and used to control the slope of the PWM ramp.
